Abstract
A communications apparatus is adapted for use with a mains electricity transmission and/or distribution network. The communications apparatus includes a signal transmission and/or reception means, and frequency conversion means for converting the frequency of a signal transmitted or received by the signal transmission and/or reception means to a frequency which facilitates improved propagation of the signal on the network. Preferably the signal transmission and/or reception means is adapted to operate according to a telephony standard with uses a relatively high carrier frequency (e.g. CT2), and the frequency conversion means is usable to covert a signal having a relatively high carrier frequency (e.g. CT2) and the frequency conversion means is usable to convert a signal having a relatively high carrier frequency to a signal having a lower carrier frequency.
